Require CUDA >=12.2

[bdice]

RSN 54 (https://docs.rapids.ai/notices/rsn0054/) states that RAPIDS will require CUDA >=12.2 in the 25.12 release.

Acceptance criteria

• Conda packages require cuda-version>=12.2 and fail to install with cuda-version=12.0
• Only one CUDA 12 build (12.2+) should exist for kvikio and cucim, both of which currently have special behavior to support CUDA < 12.2 on ARM systems (libcufile did not exist for ARM until CUDA 12.2)
• Drop CUDA 12.0 from dependencies.yaml in all repos
• All build and test matrices for RAPIDS software require CUDA >=12.2
  • e.g. ci-imgs matrix.yaml, all matrices in shared-workflows, docker matrix.yaml and matrix-test.yaml
• Documentation is updated in all repos to indicate the new minimum required version
  • Sample search: https://github.com/search?q=org%3Arapidsai+%2Fcuda.*12.0%2F&type=code
• (Optional?) rapids-cmake deprecates support for CUDA < 12.2, with removal scheduled for a future CUDA release
  • There are a few non-RAPIDS projects that require rapids-cmake, and the benefits to a 12.2 requirement are less important. I think we might be okay with no changes in rapids-cmake.

Am happy to help push this forward

@jakirkham Thanks! If you want to work on the conda packaging and dependencies.yaml updates for RAPIDS libraries, especially cuCIM and KvikIO, that'd be a wonderful next step.

rapidsai/ci-imgs, rapidsai/shared-workflows, and rapidsai/docker are already complete.

[jakirkham]

Yep was thinking the same. Thanks Bradley! 🙏

@jakirkham Any progress to share on this? I'd like to get this change in for 25.12 to align with the RSN's stated timeline.

Have added PRs to require CUDA 12.2+ in cuCIM and KvikIO

Not aware of other code cleanup cases and quick search isn't revealing anything. Though please let me know if there are others
